cc,
I have a different solution to this question. With my Fuze plugged into the computer USB port, it is charging but I can also access and listen to any content on the Fuze by using Windows Explorer to access the Fuze files and then clicking on a playlist or a single MP3 file… This activates my computer MP3 player and plays the Fuze content through the speakers/earphones connected to the computer…
This is, I believe, what you were asking about, accessing and listening to the Fuze content while connected to the computer and simultaneously charging the Fuze… Note that the Fuze is only displaying the charging screen, all control and access is actually via the computer. Doesn’t anyone else do it this way?
